We installed the loops,
hooked them into the building, flushed and purged them.
60 holes, 250 feet deep each. Each with 1 1/4" loop pipe. Every 4 holes
were fused together to a 2" header pipe and brought into the building in a
separate circuit from the other holes. The final fusion work was done
inside to bring all the 2" pipes together into the main 4" trunk.

We installed the loops,
hooked them into the building, flushed and purged them.
20 holes, 400 feet deep each. Each with 1 1/4" loop pipe. Every 4 holes
were fused together to a 2" header pipe and brought into a cement tank
outside the building. The loops were then hooked to a 4" header pipe to be
brought into the building.

This next picture is just a
small example of the custom header work that needs to be performed inside
each building. The black geothermal pipes in the picture are ready to be
fastened to the ceiling. On a finished system, they will carry a
water-based fluid from the earth-coupled ground loops into the heat pumps.
This installation is a closed loop system and the exact same fluid will be
re-circulated for the life of the system.
